Water Flashcards
To revise the structure and properties of water.
How would you draw and label two bonded water molecules?
Each molecule should have two H (delta +), one O (delta -). They should be joined with a dashed line labelled H bond
What is attraction between water molecules called?
Cohesion
Water can absorb a lot of heat energy before its temperature increases. This feature is called:
High specific heat capacity
Water absorbs a large amount of heat energy while changing from liquid water to water vapour. This feature is called:
high latent heat of vaporisation
Which is denser, ice or water, and what is the significance to life?
Ice is less dense, meaning it floats and insulates water underneath
Why is water described as a universal solvent?
It can dissolve all polar/charged molecules
What does polar mean?
The molecule has a neutral charge overall, but different charges on different parts of the molecule
